Description

Technical Field

[0001] The present application relates to the technical field of ship launching technology, and in particular to a dock and a ship launching method. Background Art

[0002] When a ship enters a dry dock for maintenance, it is usually filled with water to the same level as the river surface, the ship is then driven into the dock and the dock sluice is closed, the lake water in the dock is then pumped out and the ship is landed on the dock piers.

[0003] Since the upper height of the piers in the dock is set according to the shape of the bottom of the ship, the upper heights of the piers will be different. When the water level in the river drops, even if the dock is filled with water, the lower end of the ship will come into contact with the piers, causing the ship's floating height to fail to meet the standard and affecting the ship's launching.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the invention

[0005] In order to make the launching process of a ship more convenient after the inspection and maintenance is completed, the present application provides a dock and a ship launching method.

[0006] The present application provides a dock and a method for launching a vessel, which adopts the following technical solutions:

[0007] A dock and a method for launching a ship, comprising a fixed body, a floating body for carrying a ship, and a guide assembly for guiding the movement of the floating body, wherein the floating body is provided with a dock pier, the floating body is hollow, the floating body is provided with a first liquid driving member for extracting or injecting liquid into the floating body, the fixed body is arranged around the floating body, and a launch port for the ship to pass through is provided at one end of the fixed body away from the land;

[0008] The guide assembly comprises a guide seat slidably arranged on a fixed body, a guide member fixed on a floating body, and a guide driving member driving the guide seat to move back and forth. The upper end of the guide member is connected to the guide seat to slide vertically.

[0009] By adopting the above technical scheme, the vertical movement of the floating body drives the vertical movement of the ship. When the ship is being repaired, the amount of liquid in the floating body is reduced, so that the buoyancy of the floating body is greater than the gravity it is subjected to, thereby enabling the floating body to drive the ship to rise and detach from the water surface. When the ship needs to be launched, the floating body can be directly moved downward so that both the floating body and the ship enter the water. Thereafter, the dock on the floating body detaches from the ship. When the ship gets off the dock, the ship can be moved normally by directly moving the floating body.

[0010] Optionally: The guide seat is also provided with an adjustment component for adjusting the position of the floating body, and the adjustment component includes an adjustment seat slidably arranged on the guide seat and an adjustment driving member driving the adjustment seat to move, the sliding direction of the adjustment seat is perpendicular to the sliding direction of the guide seat, and the upper end of the guide member is passed through the adjustment seat.

[0011] By adopting the above technical solution, since the overall position of the ship is difficult to fully control after it stops, the relative position of the floating body can be adjusted so that after the floating body moves under the ship, the position of the floating body can be adjusted according to the position of the ship, so that the upper end of the dock can be aligned with the position that the ship needs to support. Then, when the floating body moves upward, the dock on the floating body can be more easily connected to the bottom of the ship, so that the floating body can stably lift the ship upward.

[0012] Optionally: the guide seat is also provided with a plurality of adjustment driving members for applying force to the side of the ship respectively, and the steel wire ropes of the adjustment driving members are used to be connected to the ship.

[0013] By adopting the above technical solution, since the ship is difficult to control when it stops, the ship may be too close to the side wall of the fixed body when it stops, making it difficult for the floating body to move directly under the ship when moving, thereby affecting the lifting of the ship. By adjusting the driving member to apply horizontal force to the ship, the position of the ship inside the fixed body is adjusted, so that the floating body can move normally to the bottom of the ship and the dock pier can be aligned with the position under the ship that needs to abut.

[0014] Optionally: the floating body is also provided with a plurality of lifting components for lifting it, the lifting components include a plurality of airbags arranged below the floating body and an inflatable member for inflating the airbags, the inflatable member is arranged on the fixed body, and the air inlet of the inflatable member is connected to the airbag.

[0015] By adopting the above technical solution, when the floating body moves into the fixed body, the inflated airbag can be used to limit the vertical displacement of the floating body, so that the upper end surface of the floating body can be lifted under the push of the airbag, so that the upper end of the floating body can be exposed above the water surface, making the floating body less likely to shake and making subsequent ship maintenance more stable.

[0016] Optionally: a plurality of support bodies are also arranged on the fixed body, and the support bodies are respectively connected to second liquid driving components for injecting and discharging liquid in the support bodies, and the second liquid driving components are arranged on the fixed body. The support bodies can move to the bottom of the floating body and support the lower end surface of the floating body.

[0017] By adopting the above technical solution, after the airbag lifts the floating body upward, by arranging the support body below the floating body, the support body is a rigid structure, so that the support body can stably support the floating body, so that the floating body can remain stable after being lifted.

[0018] Optionally: a lower fixed part is also provided in the fixed body, and the lower fixed part is arranged at a position away from the water outlet, and the upper end surface of the lower fixed part is arranged lower than the lower end surface of the floating body after floating, the airbag and the support body are both in contact with the upper end of the lower fixed part, and the floating body moves to the top of the lower fixed part.

[0019] By adopting the above technical solution, the support body and the airbag can be arranged on the lower fixed part, so that when the floating body is supported, the positions of the support body and the airbag can be stably supported, so that the floating body can also obtain stable support, making the maintenance of the ship more stable.

[0020] Optionally: the end surface of the support body close to the drain outlet is detachably connected with a connecting piece, the upper end surface of the connecting piece is lower than the upper end surface of the support body, and the lower end of the connecting piece is higher than the lower end surface of the support body.

[0021] By adopting the above technical solution, the distance and relative position between adjacent support bodies are limited by connecting parts, so that when the support body is set between adjacent airbags, the airbag will not be squeezed by the support body, so that the airbag can stably support the floating body, and when the airbag is re-inflated after being deflated, it will not be unable to expand due to being squeezed by the support body.

[0022] A method for launching a vessel comprises the following steps:

[0023] S1, inflate the airbag to lift the floating body upward until the upper end of the support body is separated from the lower end of the floating body;

[0024] S2, extracting part of the liquid in the support body, causing the support body to float upward for a certain distance until the lower end of the support body is separated from the lower fixed part, and the upper end of the support body is separated from the floating body, and the support body is pulled out from under the floating body;

[0025] S3, the airbag is deflated until the upper end and the lower end of the airbag no longer abut against each other at the same time;

[0026] S4, the guide assembly drives the floating body and the vessel above the floating body to move toward the launch port until the floating body is completely separated from the upper part of the lower fixing part;

[0027] S5. Inject liquid into the floating body to make it sink until the ship floats on the water surface, and then the ship leaves the floating body.

[0028] By adopting the above technical solution, when the ship is launched, the floating body drives the ship to move to the water surface, and then the floating body can move directly toward the bottom of the water body, so that the ship moves downward and moves into the water body. After the ship enters the water body, the ship floats in the water under the action of the buoyancy exerted by the water body, and the floating body continues to move downward so that the upper end of the dock can move downward, so that the uppermost end of the dock can be lower than the lowest end of the ship, so that the dock will not affect the movement of the ship when the ship moves, making the launching process of the ship more convenient.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The ship is supported by a floating body that can move vertically in the water. When the floating body moves upward, it can drive the ship upward so that the ship can be out of the water and can be repaired normally. After the floating body sinks, the ship can fall into the water and be raised to the surface. When the floating body moves downward, the dock pier and the ship are far away from each other, so that the normal movement of the ship is not easily affected.

[0031] 2. By setting up an airbag and a support body, after the floating body moves to above the lower fixed part, the airbag is inflated to lift the floating body. After the floating body is lifted, the support body moves to below the floating body, the airbag is deflated and the support body is used to support the floating body. The support body is a rigid structure so that the support body's support of the floating body is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] The present application discloses a dock, such as Figure 1As shown, it includes a fixed body 1 set on the land near the river, a floating body 2 for carrying ships, and a guide assembly 3 for guiding the movement of the floating body 2. The fixed body 1 is set in a rectangular frame shape with upper and lower openings. The lower end of the fixed body 1 is set on the surface of the riverbed, and a water inlet 11 for ships to enter and exit is set at the end of the fixed body 1 away from the land. The floating body 2 is set in a hollow rectangular shape. A plurality of partitions with openings are set in the floating body 2 to divide the hollow inner cavity of the floating body 2 into a plurality of spaces that can be connected to each other. The guide assembly 3 is provided with a first liquid driving member 21 for injecting liquid into and extracting liquid from the floating body 2. In this embodiment, the first liquid driving member 21 uses a two-way pump. By injecting liquid into the floating body 2, the overall weight of the floating body 2 changes, so that the floating body 2 can sink into the water. After the liquid in the floating body 2 is extracted, the weight of the floating body 2 is reduced, so that the floating body 2 can float. The surface of the floating body 2 is provided with a plurality of docks 22 according to the bottom shape of the ship, and the docks 22 are used to support the ship. The floating body 2 can move to the bottom of the ship to exert an upward buoyancy on the ship, so that the ship can move upward and leave the water surface.

[0037] like Figure 1 and Figure 2 As shown, the guide assembly 3 includes two guide seats 31 slidably disposed on the upper end of the fixed body 1, a guide member 32 fixed on the guide seat 31, and a guide driving member 33 driving the guide seat 31 to reciprocate. The guide seat 31 is disposed on the upper end of the two side walls of the fixed body 1 adjacent to the drain 11 through a guide rail. The guide driving member 33 uses a winch in this embodiment. The winch is disposed on the upper end surface of the fixed body 1. The winch is respectively disposed at both ends of the sliding direction of the guide seat 31. The steel wire rope of the guide driving member 33 is connected to the guide seat 31 to drive the guide seat 31 to move.

[0038] The guide seat 31 is also provided with an adjustment component 4 for adjusting the position of the floating body 2 relative to the ship. The adjustment component 4 includes an adjustment seat 41 slidably arranged on the guide seat 31 and an adjustment drive 42 for driving the adjustment seat 41 to reciprocate horizontally. In this embodiment, the adjustment drive 42 is a matching arrangement of a lead screw and a motor. The adjustment drive 42 is arranged on the guide seat 31, and the driving end of the adjustment drive 42 is connected to the adjustment seat 41 to drive the adjustment seat 41 to reciprocate. The lower end of the guide 32 is installed on the floating body 2, and the upper end of the guide 32 is penetrated through the adjustment seat 41 and slidably cooperates with the adjustment seat 41. The position of the floating body 2 relative to the ship is adjusted by the guide component 3 and the adjustment component 4, so that the floating body 2 can move to the correct position below the ship and lift the ship.

[0039] When the ship enters the fixed body 1, the position of the ship will be closer to one of the side walls of the fixed body 1, which makes it difficult for the dock 22 on the floating body 2 to be aligned with the bottom of the ship. Therefore, the guide seat 31 is also provided with a plurality of adjustment drive members 34 for adjusting the side strength of the ship. In this embodiment, the adjustment drive member 34 is a winch. The wire rope on the adjustment drive member 34 is connected to the side wall of the hull, so as to adjust the position of the hull relative to the fixed body 1, so that the dock 22 on the floating body 2 is easier to be aligned with the bottom of the ship.

[0040] like Figure 1 As shown, when the floating body 2 drives the ship to float, when the weight of the ship is large, it is difficult to directly drive the entire ship to float out of the water by relying solely on the floating body 2. Therefore, the floating body 2 is also provided with a lifting assembly 5 for lifting it, and the lifting assembly 5 includes a plurality of air bags 51 for lifting the floating body 2 and an inflatable member 52 for inflating and deflation of the air bags 51. The lower end of the fixed body 1 is also provided with a lower fixed portion 13, and the lower fixed portion 13 is arranged at a position away from the water outlet 11. The inflatable member 52 uses an air compressor in this application, and the air compressor is connected to the air bag 51 to inflate and deflate the air bag 51. The air bag 51 is arranged above the lower fixed body 1, and after it is above the floating body 2 and moves to the top of the air bag 51, the air bag 51 is inflated to lift the floating body 2, and the upper end surface of the floating body 2 is completely exposed to the water surface.

[0041] Since the airbag 51 will deform to a certain extent when under pressure, the stable support of the airbag 51 to the floating body 2 will be affected. Therefore, a plurality of support bodies 12 are also provided on the fixed body 1, and a plurality of second liquid driving members 14 for injecting and discharging liquid into the support bodies 12 are also provided on the fixed body 1. The second liquid driving member 14 is a bidirectional pump in this embodiment. The support body 12 is used to support the lower end of the floating body 2. The support body 12 is a rigid structure. Therefore, after the floating body 2 is pressed on the support body 12, the overall shape of the support body 12 is not easy to change, so that the floating body 2 can also obtain stable support.

[0042] In order to prevent the support body 12 from colliding with the airbag 51 when the support body 12 moves to the bottom of the floating body 2, the end surface of the support body 12 near the drain 11 is detachably connected with a connector 15, which is fixed to the support body 12 by bolts, and the upper end surface of the connector 15 is lower than the upper end surface of the support body 12, and the lower end surface of the connector 15 is higher than the upper end surface of the support body 12. The connector 15 is used to limit the position of the adjacent support body 12, so that the support body 12 is not likely to squeeze and collide with the adjacent airbag 51 when entering the bottom of the floating body 2, and the position of the airbag 51 can also be limited after the airbag 51 is deflated.

[0043] A method for launching a vessel comprises the following steps:

[0044] S1, inflate the airbag 51 to lift the floating body 2 upward until the upper end of the support body 12 is separated from the lower end of the floating body 2;

[0045] S2, extracting part of the liquid in the support body 12, making the support body 12 float upward for a certain distance until the lower end of the support body 12 is separated from the lower fixing portion 13, and the upper end of the support body 12 is separated from the floating body 2, and the support body 12 is pulled out from under the floating body 2;

[0046] S3, the airbag 51 is deflated, so that the lower end of the airbag 51 abuts against the lower fixed body 1, and the upper end of the airbag 51 is separated from the lower end of the floating body 2;

[0047] S4, the guide assembly 3 drives the floating body 2 and the ship above the floating body 2 to move toward the launch port 11 until the floating body 2 is completely separated from the upper part of the lower fixing portion 13;

[0048] S5. Liquid is injected into the floating body 2 to make the floating body 2 sink until the ship floats on the water surface, and then the ship leaves the floating body 2.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
